A phase-field investigation of recrystallization boundary migration into heterogeneous deformation energy fields: Effects of dislocation boundary sharpness

Abstract The migration of recrystallization boundaries into spatially varying deformation energy fields are simulated based on a two-dimensional phase-field model. chosen as idealized versions microstructures subdivided by two sets intersecting geometrically necessary dislocation (GNBs), and effects the sharpness GNBs investigated. simulations show that shape recrystallizing grain well kinetics considerably affected wall characteristics GNBs. Recrystallization occurs faster in deformed matrix with “sharper” walls. simulation results highlight importance microstructure kinetics, depend initial orientations, also indicate tight relations between initial, textures.
